| 07:21 | <Appiah_> hmm
| |
| 07:21 | why would you wanna change the nbi.img pmatulis ?
| |
| 07:22 | <alkisg> ...or more importantly, are you really sure you need nbi.img? :) most clients, even etherboot ones, work fine with pxelinux.0...
| |
| 07:22 | <pmatulis> Appiah_: i want to change some boot options
| |
| 07:22 | <Appiah_> pxelinux.cfg ...
| |
| 07:22 | dont need to change the .img
| |
| 07:23 | <pmatulis> Appiah_: that's for pxe clients
| |
| 07:23 | <Appiah_> O_o
| |
| 07:24 | so what's using this nbi.img then?
| |
| 07:25 | <pmatulis> well, non-pxe clients obviously

| 07:26 | <ogra_> pmatulis, search for update-kernel in the chroot
| |
| 07:27 | hanthana has quit IRC | |
| 07:27 | <pmatulis> ogra_: thanks
| |
| 07:27 | <ogra_> it had a variable that handles the options
| |
| 07:27 | something like BOOT_OPTS or so (cant remember from the top of my had and i'm not near any ltsp atm)
| |
| 07:28 | you need to manually run the update-kernels script inside the chroot after changing the var
| |
| 07:28 | and then ltsp-update-kernels outside the chroot
| |
| 07:30 | * pmatulis high fives ogra_ | |

| 09:56 | <treyh222> good morning guys
| |
| 09:57 | is there a reason that ltsp clients after starting the ltsp boot, renogiate ethernet again, with e1000_watchdog ?
| |
| 10:01 | vagrantc has joined #ltsp | |
| 10:04 | hanthana has joined #ltsp | |
| 10:05 | <sbalneav> treyh222: Well, at boot, they're under control of the pxe bios. After the linux kernel loads, it will re-initialize all hardware.
| |
| 10:07 | ajohnson has joined #ltsp | |
| 10:11 | <treyh222> sbalneav, that makes sense, ty
| |
| 10:11 | <vagrantc> sbalneav: you folks in brazil yet?
| |
| 10:13 | <sbalneav> Not yet. Sitting in jammcq's office ATM
| |
| 10:13 | plane doesn't leave 'till 5:00 pm today.
| |
| 10:13 | Overnight flight
| |
| 10:13 | <vagrantc> wheee
| |
| 10:13 | sorry i couldn't join y'all
| |
| 10:13 | <sbalneav> I've packed my bags pre-flight
| |
| 10:14 | zero hour, nine am
| |
| 10:14 | And I'm gonna be hi-iiiigh as a kite by then.
| |
| 10:14 | I miss the earth so much
| |
| 10:14 | I miss my wife
| |
| 10:14 | It's lonely out in space
| |
| 10:15 | Geez c'mon people join in: rocket man, elton john
| |
| 10:15 | vagrantc: We will miss you!
| |
| 10:15 | <vagrantc> sbalneav: heh. you'll have to do the happy packet dance without me
| |

| |
| 10:23 | <stgraber> sbalneav: hey
| |
| 10:23 | <CAN-o-SPAM> sbalneav: nice office eh?
| |
| 10:27 | <stgraber> sbalneav: was wondering, do you happen to have that ldm fix before you leave ? ;)
| |
| 10:28 | cg_uira has joined #ltsp | |
| 10:30 | <sbalneav> stgraber: I'm still testing, but I'll do some work on it down in Brazil. That's one of the reasons for going: I'll get a solid 4-5 days of LTSP hacking in.
| |
| 10:30 | Probably spend some time testing at propus.
| |
| 10:30 | right now, I'm doing some doco-hacking, before we pack up for the plane.
| |
| 10:31 | CAN-o-SPAM: Yes!
| |
| 10:31 | <stgraber> sbalneav: ok, I'm actually waiting on it before I send anything to Karmic so if you've something to test or hack, just tell me and I'll look at it.
| |
| 10:31 | <sbalneav> stgraber: expect a full fix this week.
| |
| 10:31 | <stgraber> sbalneav: btw, look for Fernando Laudares Camargos when you're there, he's one of our employees and will be attending the conference
| |
| 10:31 | <sbalneav> This is my "ltsp week"
| |
| 10:32 | <stgraber> and he's brazilian (he's actually Revolution Linux brazil ;))
| |
| 10:32 | <sbalneav> OK
| |
| 10:32 | I've written his name down.
| |
| 10:32 | I'll find him.
| |
| 10:33 | <ogra> have a beer on my bill :)
| |
| 10:33 | <sbalneav> We'll take him out for Caiprianias and BBQ
| |
| 10:33 | ogra!!
| |
| 10:33 | ogra, you did some work on the clutter based UNR desktop, right?
| |
| 10:34 | <ogra> no
| |
| 10:34 | i'm up to my arms in ARMs
| |
| 10:34 | <sbalneav> Ah
| |
| 10:34 | You have an arm notebook, yet?
| |
| 10:34 | <ogra> no GL support there (yet) ... so no clutter
| |
| 10:34 | i have the complete guts of an ARM netbook
| |
| 10:34 | but without case
| |
| 10:34 | <sbalneav> lol
| |
| 10:35 | <ogra> though given that the case for it i have seen is bright pink i'm actually pretty happy about not having it ;)
| |
| 10:35 | <sbalneav> stgraber: Does RL have an "office" per se in Brazil?
| |
| 10:35 | Hot pink. Now all you need is tailfins
| |
| 10:36 | <stgraber> sbalneav: we're a registered company in brazil and have a sort-of office in Fliorianopolis (probably wrong spelling though)

| 11:26 | <treyh222> Ok guys, I'm getting an e1000_watchdog timeout, the ethernet is not syncing fast enough, Gadi suggested that it was a NIC driver problem, so pulled a nic out of a working computer and it had the same problem, is it possible the bios needs to be flashed?

| 12:35 | <coordinador> please, how can i optimize ltsp4.2 speed?
| |
| 12:36 | <Treyh__> coordinador, why not upgrade to 5?
| |
| 12:36 | <coordinador> i have eboxII
| |
| 12:36 | <monteslu> though that surely wont help with speed :)
| |
| 12:37 | <coordinador> with ltsp5 its impossible slow
| |
| 12:37 | <Treyh__> on what distro?
| |
| 12:37 | <cliebow> 4.2 is pretty well optimized as it is...flies for me with a 200 meg processor and 32 meg ram
| |
| 12:38 | <Treyh__> coordinador, you running ubuntu as your ltsp server?
| |
| 12:38 | <coordinador> yes
| |
| 12:38 | ubuntu 9.04+ltsp4.2
| |
| 12:39 | <Treyh__> I read a lot about ubuntu and ltsp5 with those boxes is slow
| |
| 12:39 | sec still reading thread
| |
| 12:39 | * vagrantc chants ebox is the path to pain | |
| 12:40 | <Treyh__> hehe ogra's names gets mentioned a couple times
| |
| 12:40 | <vagrantc> if ltsp4.2 isn't fast enough for you, there is no LTSP known to man that is fast enough.
| |
| 12:40 | <coordinador> thanks, i tried other distros like rhel but other distros are not so easy to manage for teachers or their packages are a little old
| |
| 12:41 | <Treyh__> coordinador, how long is the boot time, 3-4 minutes?
| |
| 12:41 | coordinador, looks like an open bug https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/97456
| |
| 12:42 | <coordinador> since i turn on the server, the boxes ask for login like 3 minutes later
| |
| 12:42 | ill check..
| |
| 12:42 | <Treyh__> yea
| |
| 12:42 | ther3e are some suggestions on that link i posted
| |
| 12:42 | https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/97456
| |
| 12:43 | but they only shaved off about 20 seconds
| |
| 12:43 | <coordinador> i actually have problems with... firefox
| |
| 12:43 | when i am browsing some websites (with flash i think) firefox gets very slow
| |
| 12:44 | asmok_ has joined #ltsp | |
| 12:44 | <coordinador> and makes very difficult to navigate the website
| |
| 12:44 | <Treyh__> yea someone mentioned in there that it was an xorg problem
| |
| 12:44 | do a google search for ebox II+ltsp
| |
| 12:44 | i found a ton of articles about it
| |
| 12:45 | <Lns> vagrantc: what exactly is the issue with the eboxes? I hear so much about how horrible they are
| |
| 12:45 | never tried one myself
| |
| 12:45 | <cliebow> im not sure ogra ever found a cause for it
| |
| 12:46 | <asmok_> alkis: is it possible to use two servers, both use your ltsp-server-pnp. I found this old (2006) message: http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2006q3/000905.html
| |
| 12:46 | <alkisg> asmok_: 2 dhcp servers in proxy dhcp mode, or in normal dhcp mode?
| |
| 12:46 | What are you looking for, dhcp failover?
| |
| 12:46 | <vagrantc> Lns: they're just mysteriously slower than they should be considering the alleged specs for their hardware.
| |
| 12:47 | Treyh_ has quit IRC | |
| 12:47 | <asmok_> alkis: i have use now this howto for two server setup at school: https://wiki.edubuntu.org/EdubuntuDHCPload-balancingFailover
| |
| 12:47 | alkis: yes
| |
| 12:47 | <Lns> interesting
| |
| 12:49 | <alkisg> asmok_: I think it's too much of a hack... why not use gpxelinux.0, and then gpxe.priority to set the primary / secondary etc server?
| |
| 12:50 | <asmok_> how about that "Dispatching method" with LDM? http://www.ltsp.org/~sbalneav/LTSPManual.html#id2538155
| |
| 12:50 | <alkisg> dhcp failover is a different thing than load balancing, which one are you looking for?
| |
| 12:50 | <asmok_> not very familiar with gpxelinux, but i try to leran that too
| |
| 12:52 | dhcp failover, see my files here, two identical servers:
| |
| 12:52 | http://www.arkki.info/howto/Wiki/LTSP5-Mantykangas/ltsp-master/
| |
| 12:52 | http://www.arkki.info/howto/Wiki/LTSP5-Mantykangas/ltsp-slave/
| |
| 12:53 | Drakonen has left #ltsp | |
| 12:53 | <asmok_> that one works very well so no need another setup, just wonder what we can do with ltsp-server-pnp
| |
| 12:53 | <alkisg> Well, I don't think dnsmasq supports dhcp peers, so I doubt that ltsp-server-pnp will be of any help for dhcp failover..
| |
| 12:54 | <asmok_> ok good to know from developer himself ;-)
| |
| 12:54 | <alkisg> I'm not actually sure, you have to ask in dnsmasq list
| |
| 12:55 | What you _could_ do is let the router assign dhcp leases; this may (or may not) be more stable than an ltsp server assigning leases
| |
| 12:55 | (e.g. should be less prune to updates, hangs etc)
| |
| 12:55 | In this case, yes, you could use dnsmasq in proxy mode
| |
| 12:55 | (in both servers)
| |
| 12:55 | <asmok_> ok i will check that option too
| |
| 12:56 | bieb has joined #ltsp | |
| 12:56 | <coordinador> what is more efficient for eboxII (slow) machines? esd or pulseaudio (assuming that pulseaudio will work with that boxes)
| |
| 12:57 | <alkisg> And a third option, is to put as many servers as you want, but on different ranges, and let the clients get the lease from whatever server sends the first offer :D
| |
| 12:57 | (hack hack hack :D)
| |
| 12:57 | <asmok_> I'm no hacker...
| |
| 12:58 | how far is ltsp-cluster thing? is it possible to test on KVM virtual machines, there is no documentation...
| |
| 12:59 | bieb has left #ltsp | |
| 13:00 | bieb has joined #ltsp | |
| 13:02 | <asmok_> alkis: by " let the router assign dhcp leases" do you mean something like this? http://wwwn.dd-wrt.com/wiki/index.php/Dual_WAN_with_failover
| |
| 13:03 | <alkisg> asmok_: no, I mean the usual dhcp service provided by the routers...
| |
| 13:04 | <asmok_> ok, thanks
| |
| 13:05 | <alkisg> asmok_: e.g.: http://www.cisco.com/en/US/docs/ios/12_0t/12_0t1/feature/guide/Easyip2.html#wp4363
| |
| 13:05 | barbosa has quit IRC | |
| 13:05 | <alkisg> How frequently does a router crash?
| |
| 13:05 | <vagrantc> depends on the router...
| |
| 13:06 | i'd be more inclined to trust a real linux server...
| |
| 13:06 | * alkisg would rely on the router - on a school environment, that is.. :D | |
| 13:06 | <alkisg> It's not that I don't trust us teachers, but well... I don't trust us :)
| |
| 13:08 | <asmok_> i have used my setup for over two years now, first setup was Ubuntu 6.06+ltsp4.2, now Ubuntu 8.04, it has been very stable
| |
| 13:08 | <alkisg> asmok_: do the teachers have administrative access to the ltsp servers?
| |
| 13:09 | <asmok_> no, not at all, it's my daughter's school, so i just check things when i pick her ;-)
| |
| 13:10 | <alkisg> Heh... trying to get better marks for your daughter? ;)
| |
| 13:10 | <asmok_> elementary school: http://www.mantykankaankoulu.kokkola.fi/
| |
| 13:11 | yes ;-) of course
| |
| 13:11 | <alkisg> My wife got to finland three years ago; she was impressed by your edu system...
| |
| 13:12 | Treyh_ has joined #ltsp | |
| 13:12 | <pmatulis> is the use of pulseaudio in ltsp documented somewhere special? or is it non-ltsp (generic) stuff?

| 13:14 | <asmok_> sad thing is that school is only one in our town - all others schools use W. it is long story why that one school have all on L ;-)
| |
| 13:15 | but now i have to leave, bye - and thanks Alkis - i study more about dnsmasq and routers, good night
| |
| 13:15 | asmok_ has left #ltsp | |
| 13:15 | <alkisg> In my town I "converted" 2 schools to LTSP... one per year, in a few years i'll get a good percentage :D
| |
| 13:17 | <bieb> are there any issues I should be on the lookout for running LTSP on Ubuntu 64 bit?
| |
| 13:19 | <Lns> alkisg: =) Keep us all updated, remember to edit the ltsp wiki to document your installs
| |
| 13:19 | <alkisg> Lns, what?
| |
| 13:19 | We have a wiki for ltsp installations?
| |
| 13:19 | <Lns> alkisg: ;) http://wiki.ltsp.org/twiki/bin/view/Ltsp/SuccessStories
| |
| 13:20 | <alkisg> Woah!
| |
| 13:20 | <Lns> hahaha
| |
| 13:20 | <alkisg> It'll be the first ones for Greece :D OK, will do it sometime in the summer

| 13:23 | <alkisg> Don't expect much; just ancient PCs and a brand new server...
| |
| 13:23 | ~500€ budget per lab
| |
| 13:24 | <Lns> sure, but that's one more success!
| |
| 13:25 | <bieb> Lns: you part of ALE too?
| |
| 13:25 | <Lns> bieb: ale?
| |
| 13:25 | I like to drink ale... ;)
| |
| 13:25 | <bieb> Atlanta Linux Enthusiasts
| |
| 13:25 | <Lns> bieb: nope, i'm out in california :)
| |
| 13:26 | <bieb> ok
| |
| 13:26 | <epsas> i remember the atlanta linux showcases
| |
| 13:27 | <bieb> epsas: they were started by the members of ALE
| |
| 13:28 | <epsas> yeah
| |
| 13:28 | <bieb> some of those guys are still around and come to the meetings
| |
| 13:29 | there was a new linux showcase type event ... it was at Clemson University South East Linux fest
| |
| 13:29 | <epsas> in south carolina?
| |
| 13:29 | nice
| |
| 13:29 | intelliant has quit IRC | |
| 13:29 | <epsas> their school of agriculture sells nice milkshakes and ice cream. i'd go there again
| |
| 13:32 | <Lns> nothing like ice cream as human bait ;)
| |
| 13:33 | <bieb> :D
| |
| 13:34 | and it has been said that Clemson has a female student population that is very easy on the eyes :D
| |
| 13:44 | <coordinador> what if im running ltsp4.2
| |
| 13:44 | and i want to use ltsp5 in some machines
| |
| 13:44 | i know there is a manual for that
| |
| 13:44 | but,,, now the system is in use...
| |
| 13:44 | is it to risky?
| |
| 13:45 | is too risky install ltsp5 now, with the system in use?
| |
| 13:46 | <vagrantc> coordinador: i think ltsp 4.2 supports installing in /opt/ltsp-4.2 or soemthing like that, so it'll keep everything separate.
| |
| 13:46 | shouldn't be too hard to have both.
| |
| 13:47 | <coordinador> im scary, but ill do :S in this moment
| |
| 13:47 | dont go pls, in case everything becomes a mess
| |
| 13:47 | thanks haah
| |
| 13:55 | if i have ubuntu 9.04 and i want to have ltsp5, can i install it via apt-get ?
| |
| 13:57 | ok, i found the answer
| |
| 13:58 | Faithful has quit IRC | |
| 14:06 | <bieb> sbalneav: you around?
| |
| 14:15 | <cliebow> coordinador, dhcp should be able to take care of the ltsp4.2/5 switching...i do it for netvista,standard and ibooks..some served from windows dhcp..some from linux..
| |
| 14:21 | <coordinador> thanks
| |
| 14:24 | <cliebow> because it is the initramfs that makes a call to the server for an nbd mount(ltsp5) or nfs mount..
| |
| 14:26 | <coordinador> now im 4.2 already installed, but in website they say that i have to install ltsp5 first.. do ill have any difficulty if i install ltsp5 after ltsp4.2?
| |

| |
| 14:29 | <cliebow> coordinador, the ltsp5 will overwrite things like default position of dhcpd.conf..to be safe just move /opt/ltsp/i386 to a nice safe place..first
| |
| 14:30 | artista_frustrad has quit IRC | |
| 14:30 | <cliebow> default directory for tftp will prob change as well..so put your old tftpdirectory in a safe place as well..
| |
| 14:33 | <Lns> Gadi: ping
| |
| 14:36 | <cliebow> the gadmeister is out i am afraid
| |
| 14:36 | we'll have to dock his pay..
| |
| 14:37 | <Lns> cliebow: ;) He's not still in CA is he?
| |
| 14:37 | <cliebow> i dont know..
| |
| 14:38 | <nubae> hiya Lns

| 14:39 | <nubae> Going to Berlin tomorrow for Linxutag...wonder if ubuntu will be represented... I suppose so in some form or another...
| |
| 14:39 | <pmatulis> what's the use of a sshfs mount for a user's home directory?
| |
| 14:49 | <Gadi> Lns: pong
| |
| 14:49 | <Lns> Gadi: hey! how'd that install go?
| |
| 14:50 | <Gadi> it went
| |
| 14:50 | :)
| |
| 14:50 | <Lns> =p~
| |
| 14:50 | <Gadi> they should be using it today with a class
| |
| 14:50 | haven't heard anything yet
| |
| 14:50 | <Lns> woo! nice. You're obviously not out here anymore right?
| |
| 14:50 | <Gadi> nope
| |
| 14:50 | home since Tuesday AM
| |
| 14:50 | <CAN-o-SPAM> how many G?
| |
| 14:51 | <Gadi> I dunno, 30uish
| |
| 14:51 | *30ish
| |
| 14:51 | atm
| |
| 14:51 | nothing (yet) to write home about
| |
| 14:51 | :)
| |
| 14:52 | though, I must say, I like schools with VLAN switches
| |
| 14:52 | <CAN-o-SPAM> at DisklessWorkstations.com, we pilot with smiles! haha :)
| |
| 14:52 | gig infrastructure too?
| |
| 14:52 | <Gadi> hmm.. good question - I didn't really ask :)
| |
| 14:54 | pmatulis: we use sshfs for the home dir for local apps
| |
| 14:54 | * Lns hopes at least the server had a gigabit link.... :/ | |
| 14:54 | <Gadi> Lns: oh yeah
| |

| |
| 14:54 | <pmatulis> Gadi: ah
| |
| 14:54 | <Lns> nice..bonded?
| |
| 14:54 | <pmatulis> Gadi: thanks
| |
| 14:54 | <Gadi> pmatulis: np
| |
| 14:54 | Lns: not at the moment
| |
| 14:54 | :)
| |
| 14:55 | <Lns> That's so funny, because I just put up a vid about bonding last week..horrible quality, but I'm going to re-do it at my next school deployment (probably today) - http://www.youtube.com/watch?v=cy9SCPeYXIQ
| |
| 14:55 | at the least the video shows the basics of how it works
| |
| 14:55 | <Gadi> thats funny - someone over the weekend told me they saw my presentation to the local LUG from 2 years ago online
| |
| 14:55 | how embarrassing
| |
| 14:56 | hours of video of watching urself talk
| |
| 14:56 | :)
| |
| 14:56 | <Lns> hehehe
| |
| 14:56 | <Gadi> worse, its the first result on google for "gideon romm ltsp"
| |
| 14:56 | :P
| |
| 14:56 | * Lns googles quickly =p | |
| 14:56 | * Gadi needs to start seeding the search engine with links to porn | |

| 15:08 | <Treyh_> Gadi, Hiya
| |
| 15:09 | Gadi, remember that issue I had last week with the nic and it was probably a driver issue?
| |
| 15:09 | times out on e1000_watchdog and gives kernel panic
| |
| 15:11 | <Gadi> ah
| |
| 15:11 | so it is an e1000 bug?
| |
| 15:11 | there was one floating around
| |
| 15:11 | <Treyh_> well I put in a 3com card
| |
| 15:11 | the original was an onboard
| |
| 15:12 | and the problem continued
| |
| 15:12 | <Gadi> same error?
| |
| 15:12 | <Treyh_> the onboard is a 10/100/1000 but the 3com is a 10/100. tried on a gig switch and a 10/100 switch
| |
| 15:12 | yes
| |
| 15:12 | <Gadi> e1000_watchdog timeout on the 3com card?
| |
| 15:13 | <Treyh_> yes, I will type out the exact error, it's booting up now
| |
| 15:13 | <Gadi> okey dokey
| |
| 15:13 | japerry has quit IRC | |
| 15:14 | <Treyh_> k it's working on timing out now
| |
| 15:16 | k got it
| |
| 15:16 | coordinador has quit IRC | |
| 15:16 | <Treyh_> i'll pastebot it

| 15:17 | <ihernandez> hello. i'm searching the web and docs but can't find how to make sessions persistent
| |
| 15:17 | let's say. a PXE client start a session, he has a problem and the connection is lost or the thinclient goes down... i want the LTSP to keep his session running. is that possible?
| |
| 15:17 | <ltsppbot> "Treyh_" pasted "IP-Config: eth0 hardware addre" (5 lines) at http://pastebot.ltsp.org/384
| |
| 15:18 | <Treyh_> Gadi, ok I pasted it
| |
| 15:18 | <Gadi> did you disable the onboard NIC in the BIOS?
| |
| 15:18 | <Treyh_> yes
| |
| 15:18 | and it's not plugged in either
| |
| 15:18 | <Gadi> edit your pxelinux.cfg file and add to the line: break=mount
| |
| 15:18 | and reboot
| |
| 15:19 | you will be at an initramfs prompt
| |
| 15:19 | <Treyh_> k sec
| |
| 15:19 | <Gadi> ihernandez: LDM sessions cannot persist
| |
| 15:19 | you need to use a different protocol, such as NX
| |
| 15:20 | <ihernandez> Gadi, I see. Thanks.
| |
| 15:20 | <Gadi> peristence requires the use of a caching X proxy
| |
| 15:20 | <Treyh_> Gadi: this look right: cnc@ltsp:/var/lib/tftpboot/ltsp/i386/pxelinux.cfg$ sudo vi default
| |
| 15:20 | DEFAULT vmlinuz ro initrd=initrd.img break=mount
| |
| 15:20 | <Gadi> in other words, the session talks to an X proxy that caches it and then relays the display to the X server
| |
| 15:21 | <Treyh_> DEFAULT vmlinuz ro initrd=initrd.img break=mount
| |
| 15:21 | <Gadi> Treyh_: perfect
| |
| 15:21 | <Treyh_> k rebooting client
| |
| 15:21 | <Gadi> when you get to the prompt, you can look a little closer at a few things
| |
| 15:21 | like:
| |
| 15:21 | ls /sys/class/net/
| |
| 15:21 | (to see which interfaces it knows about)
| |
| 15:21 | or ifconfig
| |
| 15:21 | etc
| |
| 15:22 | then, we can load the drivers by hand and see if/why they fail
| |
| 15:22 | <Treyh_> k
| |
| 15:25 | ok ifconfig is blank
| |
| 15:26 | ls /sys/class/net shows eth0 and lo
| |
| 15:26 | <Gadi> blank?
| |
| 15:26 | you mean, no IPs
| |
| 15:26 | <Treyh_> ifconfig just returned nothing
| |
| 15:27 | <Gadi> try: /sbin/ifconfig
| |
| 15:28 | <Treyh_> not found
| |
| 15:28 | /sbin/config not found lol
| |
| 15:29 | there is an /bin/ipconfig
| |
| 15:30 | <Gadi> right
| |
| 15:31 | one sec
| |
| 15:31 | <Treyh_> k
| |
| 15:32 | <Gadi> try: ipconfig eth0
| |
| 15:33 | <Treyh_> k
| |
| 15:33 | ok
| |
| 15:33 | it pulled an ip from the dhcp server
| |
| 15:33 | all looks correct
| |
| 15:34 | hmmm it did say thoug IP-Config: eth0 guessed broadcast address: 172.16.255.255
| |
| 15:34 | weird word to use: guessed
| |
| 15:35 | <Gadi> well, I guess it was not provided one explicitly
| |
| 15:35 | but derived it from the netmask
| |
| 15:35 | <Treyh_> k
| |
| 15:35 | <Gadi> now, it would appear to me that you have a race condition, perhaps
| |
| 15:35 | <Treyh_> race condition?
| |
| 15:36 | <Gadi> in other words, two things are going on independently:
| |
| 15:36 | 1. the NIC driver has to be loaded
| |
| 15:36 | 2. ipconfig has to request an IP
| |
| 15:36 | if #2 happens before #1, you fail
| |
| 15:36 | <Treyh_> gotcha
| |
| 15:37 | seems like thats what is happening
| |
| 15:37 | <Gadi> #2 should only happen on condition of 1
| |
| 15:37 | <Treyh_> is there a way to extend that 60 second timeout?
| |
| 15:37 | <Gadi> I don't think thats the problem
| |
| 15:37 | that timeout is waiting for an answer from the server
| |
| 15:37 | not for the driver to start
| |
| 15:37 | lets do an experiment, shall we?
| |
| 15:38 | <Treyh_> i'm game
| |
| 15:38 | <Gadi> cool
| |
| 15:38 | ok, on the server, do: sudo chroot /opt/ltsp/i386
| |
| 15:38 | actually, what editor do you like to use
| |
| 15:38 | to edit files?
| |
| 15:38 | <Treyh_> vi
| |
| 15:38 | <Gadi> cool
| |
| 15:39 | once chrooted, vi /usr/share/initramfs-tools/scripts/ltsp_nbd
| |
| 15:39 | <Treyh_> sudo chroot failed
| |
| 15:39 | don't think it like sudo
| |
| 15:39 | <Gadi> ok
| |
| 15:39 | well, chroot in as root
| |
| 15:39 | :)
| |
| 15:41 | <Treyh_> tried su
| |
| 15:41 | it failed
| |
| 15:41 | tried just chroot
| |
| 15:41 | said no such file or directory /opt/ltsp/i386
| |
| 15:41 | <Gadi> huh?
| |
| 15:41 | on the ltsp server?
| |
| 15:41 | <Treyh_> lol
| |
| 15:41 | <-- moron i'm on the client
| |
| 15:41 | sec
| |
| 15:42 | ok i have the ltsp-nbd open
| |
| 15:42 | ltsp_nbd open
| |
| 15:43 | <Gadi> ok, scroll down until you see "configure_networking"
| |
| 15:43 | see it?
| |
| 15:43 | <Treyh_> yes
| |
| 15:43 | <Gadi> before that line, add a line that says "sleep 3"
| |
| 15:44 | and save the file
| |
| 15:44 | then, when you are back at the prompt, do an:
| |
| 15:44 | <Treyh_> k saved
| |
| 15:44 | <Gadi> update-initramfs -u
| |
| 15:44 | then, exit out of the chroot
| |
| 15:44 | <Treyh_> done
| |
| 15:44 | k
| |
| 15:44 | <Gadi> and do a:
| |
| 15:44 | sudo ltsp-update-kernels
| |
| 15:45 | <Treyh_> done
| |
| 15:45 | <Gadi> then, take out the break=mount
| |
| 15:45 | from the pxelinux.cfg/default file
| |
| 15:45 | and reboot the client
| |
| 15:45 | <Treyh_> k
| |
| 15:45 | rebooting now
| |
| 15:46 | <Gadi> hopefully, 3 seconds is enough to let the driver load
| |
| 15:46 | <Treyh_> Gadi, whether this works or not, you really are the man
| |
| 15:47 | <Gadi> well, we're just tracing atm
| |
| 15:47 | :)
| |
| 15:47 | a little bit of experimentation
| |
| 15:47 | these race conditions are some of the pitfalls of all this "let's speed up the boot time by running things in parallel"
| |
| 15:48 | that only works for things that are independent
| |
| 15:48 | <Treyh_> i see
| |
| 15:48 | <Gadi> but, these are dependent functions
| |
| 15:48 | ipconfig is the "y" to the driver's "x"
| |
| 15:48 | for those math folks in the audience
| |
| 15:48 | :)
| |
| 15:49 | <Treyh_> lol
| |
| 15:49 | ok slightly different error this time
| |
| 15:49 | <Gadi> ok
| |
| 15:49 | <Treyh_> ip-config: no response after 60 secs - giving up
| |
| 15:49 | init: .: line 1: can't open t/mp/net-etho0.conf
| |
| 15:49 | so similiar but not the same
| |
| 15:50 | <Gadi> isnt that what we got the last time?
| |
| 15:50 | <Treyh_> IP-Config: eth0 hardware address 00:01:02:c4:cb:43 mtu 1500 DHCP RARP
| |
| 15:50 | : 2.971340) eth0: setting full-duplex
| |
| 15:50 | IP-Config: no response after 60 secons - giving up
| |
| 15:50 | init: .: line 1: can't open /tmp-net-eth0.conf
| |
| 15:50 | Kernel Panic
| |
| 15:50 | is what i got last time
| |
| 15:51 | <Gadi> ok, lets get a little more sophisticated
| |
| 15:51 | <Treyh_> k
| |
| 15:51 | and if you would like
| |
| 15:51 | i can try the onboard nic again
| |
| 15:51 | <Gadi> go back to the server, and chroot in, and vi that file again
| |
| 15:51 | <Treyh_> instead of the 3com
| |
| 15:51 | k
| |
| 15:52 | i'm there
| |
| 15:52 | <Gadi> now, instead of a simple "sleep 3"
| |
| 15:52 | <Treyh_> oh wait
| |
| 15:52 | shit
| |
| 15:52 | i put sleep3
| |
| 15:52 | instead of sleep 3
| |
| 15:52 | <Gadi> oh...
| |
| 15:52 | ok, lets fix that first
| |
| 15:52 | :)
| |
| 15:52 | spelling counts
| |
| 15:53 | ihernandez has quit IRC | |
| 15:53 | <Gadi> the computer's a strict teacher
| |
| 15:53 | <Treyh_> lol
| |
| 15:54 | rebooting the client now
| |
| 15:54 | elisboa has quit IRC | |
| 15:54 | <Treyh_> did both the updates command first of course
| |
| 15:54 | jonathan1 has joined #ltsp | |
| 15:55 | <Gadi> ok, you did an update-initramfs -u
| |
| 15:55 | <Treyh_> yes
| |
| 15:55 | <Gadi> and the ltsp-update-kernels, too?
| |
| 15:55 | <Treyh_> and then exited the choort and di that
| |
| 15:55 | <Gadi> cool
| |
| 15:55 | <Treyh_> oops
| |
| 15:56 | i copied back over the original instead of the quiet splash lol
| |
| 15:56 | the pxelinux.cfg/default
| |
| 15:56 | no
| |
| 15:56 | it still says quiet splash
| |
| 15:56 | but it wasn't quiet?
| |
| 15:56 | DEFAULT vmlinuz ro initrd=initrd.img quiet splash
| |
| 15:56 | is my pxelinux.cfg/default
| |
| 15:57 | but i saw the splash screen?
| |
| 15:57 | <Gadi> yeah, ltsp-update-kernels, prolly put it back
| |
| 15:57 | you can take out the quiet and splash
| |
| 15:57 | <Treyh_> ok i took it out
| |
| 15:57 | now what
| |
| 15:57 | still got a kernel panic
| |
| 15:58 | <Gadi> ok, first, add back the break=mount
| |
| 15:58 | <Treyh_> k
| |
| 16:01 | k added
| |
| 16:02 | Gadi, and rebooting the client now
| |
| 16:05 | <Gadi> ok
| |
| 16:05 | <Treyh_> Gadi, ty for your help again, I have to run, will ttyl
| |
| 16:05 | <Gadi> ok
